Topic: ZU "not responding" (Read 11906 times)

I have been using ZU for a year and usually it has worked well. Lately, when uninstalling an analyzed app, it seems to take quit a long time, but eventually it gets done. However, today after about 10 mins I checked the Task Manager, and it indicated that ZU was not responding. I ended task and the app was still listed in the analyzed list of apps. Interestingly, the app I was removing was a trial version of Total Uninstall.

I tried uninstalling Total Uninstall with ZU again and monitored it with Task Manager. For about a minute, ZU was "running", then for several minutes ZU was "not responding", then ZU started "running" again for a couple of minutes, and finished the uninstall.

I then used ZU to uninstall another app (PDF-XChange Viewer) and it sped through the process perfectly and never went through a period of "not responding".

So this seems to be an issue specific to using ZU to uninstall Total Uninstall.

What would be the explanation for this isssue? Is this likely to occur when uninstalling other apps?

Well... The 'not responding' thing in windows doesn't really mean that the program isn't doing anything...The reason that sometimes it's 'not responding' is, that the uninstall-module is in the same thread as the gui interface... what this means is, that the gui interface (for instance, that another line is added to the log, for instance 'xyz was deleted') isn't updated in the timespan where a file is actually being deleted... So, if it is deleting a lot of files that each take a long time, it will 'stop responding' (according to windows)... (I suppose this could happen if a lot of files are in use, for instance)...

A 'solution' would be to move the uninstall-process into another thread... I'll look into that...

Thanks for the explanation and your future efforts to correct this problem.

If you want to replicate the problem, you could download and install a trial version of Total Uninstall (www.martau.com) using ZU, and then do the uninstall with ZU.

I was surprised by this problem because I have used ZU to uninstall large apps like MS Office which was very fast. Whereas, Total Uninstall is only a 7mb installation. So something odd is happening here.

Again, I installed and uninstalled Total Uninstall with ZU, while I was off the network.

I got the same results. In the middle of the uninstall process ZU began "not responding" and after a couple of minutes, ZU started "running" again, and finished the uninstall process. I checked this with the Task Manager. During the time that ZU was "not responding", there were two entries of ZU in the Task Manager and each said "not responding".

This problem occassionally happens when I uninstall other apps with ZU.

I am wondering what the problem is and whether the new v. 2.5 will correct this. Is v. 2.5 near release?
